The opportunity

We are working with a deep-tech company developing advanced optical and electronic systems for highly secure communications.

They are looking for an Electronics Engineer with strong experience across analogue circuit design, digital interfaces, PCB development and optoelectronic hardware. You will work alongside physicists, optical engineers, embedded developers and hardware specialists to turn complex scientific concepts into reliable, deployable products.

This is a hands-on R&D position where you will design, build, test and troubleshoot electronics used alongside lasers, optical components and highly sensitive detectors.

What you’ll be doing

• Design analogue and mixed-signal electronics for advanced photonic systems
• Develop low-noise circuits for sensitive optical detectors and measurement equipment
• Create driver electronics for lasers, optical sources and other high-speed components
• Design digital interfaces connecting sensors, controllers, FPGAs and embedded processors
• Produce complete PCB designs, including schematic capture, component selection and board layout
• Develop boards containing high-speed signals, precision timing and sensitive analogue circuitry
• Build and test prototypes before supporting the transition into repeatable production hardware
• Carry out board bring-up, debugging, signal analysis and root-cause investigation
• Use oscilloscopes, spectrum analysers, logic analysers and other laboratory equipment to validate performance
• Work closely with optics and physics teams to translate experimental requirements into practical electronic systems
• Integrate lasers, photodetectors, timing electronics and control hardware into complete products
• Define component-level and system-level test procedures
• Improve existing designs for noise performance, signal integrity, stability, reliability and manufacturability
• Support system integration, environmental testing and field deployment
• Create clear design records, test reports, user documentation and technical specifications
• Contribute to project planning, technical proposals and customer-facing engineering discussions

What we’re looking for

• A degree in Electronics Engineering, Electrical Engineering or a closely related discipline
• Professional experience designing and testing analogue and digital electronic systems
• Strong knowledge of analogue circuit design, including amplification, filtering, signal conditioning and power regulation
• Experience designing low-noise or high-sensitivity electronics
• Practical understanding of mixed-signal PCB development
• Experience with schematic capture, PCB layout and design-for-manufacture principles
• Knowledge of signal integrity, grounding, shielding, impedance control and electromagnetic compatibility
• Experience interfacing digital components through protocols such as SPI, I²C, UART, USB or Ethernet
• Comfortable selecting electronic components and assessing technical trade-offs
• Strong hands-on laboratory skills, including board bring-up and fault diagnosis
• Experience working with embedded processors, microcontrollers or FPGA-based systems
• Ability to work effectively within a multidisciplinary R&D environment
• Clear technical documentation and communication skills

Particularly relevant experience

Candidates do not need to cover every area below, but experience with any of the following would be highly valuable:

• Optoelectronic or photonic systems
• Photodiodes, avalanche photodiodes or single-photon detectors
• Transimpedance amplifiers and low-noise front-end electronics
• Pulsed laser drivers or laser-diode control circuits
• Precision timing, time-to-digital conversion or time-stamping systems
• High-speed data acquisition and signal processing
• LiDAR, optical communications, scientific instrumentation or imaging systems
• FPGA integration and real-time hardware control
• Space, aerospace, defence or other high-reliability electronics
• Environmental, vibration, thermal or electromagnetic testing
• Quantum technologies or secure communications

Why consider it?

• Work on electronics operating at the boundary of engineering, photonics and advanced physics
• Take ownership across the complete hardware lifecycle, from early circuit design to deployed systems
• Build products involving lasers, sensitive detectors, precision timing and high-speed electronics
• Join a specialist deep-tech environment where individual engineers have meaningful technical influence
• Work directly with experts across electronics, optics, embedded software and physics
• Contribute to hardware designed for demanding, real-world applications rather than purely laboratory research
